All-optical modulation is achieved in a microfibre coil resonator functionalized with black phosphorus nanosheets. The modulation properties of the device are regulated based on BP absorption, photo-thermal, and optical Kerr effects, resulting in good response time and responsivity. The device could have potential applications as an all-optical modulator, optical switch, or tunable optical filter.
All-optical modulation is experimentally demonstrated in a microfibre coil resonator (MCR) functionalized with black phosphorus (BP) nanosheets (BP-MCR). The BP nanosheets is deposited onto microfibre and then microfibre is wrapped on a PMMA rod covered with UV-curable low refractive index polycarbonate (PC) resin. The BP-MCR modulation properties are regulated based on BP absorption, photo-thermal and optical Kerr effects. The resonance wavelength and extinction ratio responsivity to incident pump power can attain similar to 0.033 nm mW(-1) and similar to 0.180 dBm mW(-1), while the averaged rising/falling response time is similar to 9.58/8.53 ms. The device could find applications as all-optical modulator, optical switch or tunable optical filter.
